Figure 3 is a perspective view fromathe same aspects as Figures 1' and2, showing ;the:article of furniture made up as a bed. a 11- Figure 4 isa vertical sectional.view-;on-an:en.- larged scale, taken on they line'4-14"of.rFigure;1i", with the direction of view. as indicatedshowingthe'upholstery cushion of the davenport back in conventional position,and, in broken line, moved to a position permitting thedavenport to becon verted to a bed. i 1' Figure 5 is. a fragmentary'detail from: Figure'4, on a further enlarged scale, showing the method of attaching theback upholstery of the v davenport to the back support.

Figure 6 is another fragmentary sedtionalqdetail onlapproximately thescale of Figure15, and taken on the line 6-6 of Figure 4, with the direction of 'view as indicated, showing the means used to mount the backsupport of the davenport pivotally upon the arm-rests. 1 I v Figure '7is a horizontal sectional view on the plane of section indicated by theline 1-4 of Figure 6, showing means for controlling the pivotal movementof the -davenport back support. Figure 8 is a vertical fragmentary:sectional detail on a further enlarged scale, taken onthe plane ofsection indicated by the line'8'-" -8lof Fig-" Having reference now tothe details of-the drawings, #my improved convertible bed and davenportmay comprise a main frame Ii supporting a seat mattres's' 'll andhavingarm-restsi l3 at each end secured to the frame and forming" partthereof. -One or more of the arm-re'sts is may contatin a compartmenti4, closable by 'a 'Ihe'frame H and the seat mattress l2 may havethew'idth of a standard single bed;

door I 5 and of coursethe length of theiseat 'mattress l-23 betweenth'earm-rests I3 is ofsuitable' lengthf" for a bed.

Each of the arm-rests l3 haspivotally mountedthereon, as shown in detailin Figures 4.:to B,

a back support 11. The two back supportsii'l; are each substantiallyhalf the length-:of, the: seat mattress [2 so as to be adapted to beswun to each of the back supports I1, extending nori mally downwardlyover the frontal face lfliof' the back support to substantial contiguitywith the seat mattress l2 and forming a closure for the cabinet 28. Thecushions 22 may besecured' to the back supports I! in any suitablemanner permitting them to be swung upwardly, as shown in broken line inFigure 4, but preferably I employ a hinge connection, asshown in Figure5,

which' permits the cushions 22 to be easily disengaged and removed fromthe back supports. Plates 23 are inserted in the upper panelling 25 ofthe back supports H; and haveslots"25 for receiving hooks lfisec'ured:to the rearward sides of the cushions 7,2. F The forward-imargins'21 0fthe plates 23, definin'gthe'sl'ots 25 form adequate hinge bars'f'ror'nwhich the hooks. 26 may be easily disconnected V Y, Each of theback-supports -11 is pivotallybecured by a' 'bearingbracket. 25.! to apivot post $0,:as:sliown-f in-"Figure 6, the post 39 extendingdownwardly into the arm-rest |3.:andi there being mounted in a bearingbracket 31'. 'AJcoHar-BZ on the post 3i!v provides; asuppcrtinglibearing for theback support ll, separatingthe lowersurfaceof the back support and theupper surface of arm-rest l3 sufficiently topermit swinging' 'the biackxsupport without friction on the arm-rest.rr' To limit the pivotarmovenrent cf'the back supportsfllfl to movementbetween the aligned positions above described invrhich' they form asofazback, and positions in upward extension of the arm.-- .:ests I3, inwhich they form head and foot members for a bed, a plate 34 is securedto the lower surface of each back support and has an arcuater'slot 35describing an'arcof substantially ninety degrees. A plate'tt securedto'theupper surface of thearm-rest 13 serves to locate apost 31, theupper'end of which is adaptedetor travel in thecslot 35. The post 31,accordingly, stops further pivotal; movement of: tlreback support-l 1:whenever either: end of the slot -35 comes into contact with-it.*W-henmy convertible v bed-and davenportis to; be used as a davenport,the back supports?" are; swung into alignment'abovethe rearward marginof the frame H and seat mattress l2, and ,the upholstery cushions 22 areallowed tohang naturally fromthe hinge bars 27,. as shown iii-Figural.The cushions 22'then cover the cabinets 20 and extend downwardly totheseatmattress l2, and are projected forwardlywby the inclinedv faces I8of the back supports ll, so as' to' reduce. the effective width of theseatmattress" l=2i-to a width appropriate for a davenport'seat; Toconvertthearticle of furniture toa bed, it is merely necessary to raisethe cushions 22, as shown in Figure 2, so as to clear the arm-rests l3),and to swing the back supports IT to the positions shown in Figures, inupward extension of the arm rests. The cushions 22 are-then allowed todrop as closures to the cabinets 20.

4 In this position, the back supports I! form adequate head and footmembers for a bed, permitting pillows tobe banked against either supportin a manner comfortable to a person sitting up in bed. Blankets andsheets may be tucked between the seat mattress l3 and the frame H, aswith an ordinary bed, as the seat mattress does not overhang the frame.The cabinets 20 are asreadily accessible as thecabinet [4, providingspace for storing personal articles:
